To all when?, 'it .may concern:

Be it known that I, GEORGE H. GERE, a

citizen of the United States, residing at Utica,

in the county ofUneida and State 'of New York, have invented certain newand use- 'ful'improvcments in Carbureters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as vwill enable others skilled in the art to which it appertains to make and use the j same.

My inventionr relates to-improvements in carbureters; and its object is toprovide iinproved means for controlling the' ilow of gasolene to the same, 'to provide improved means Ai'or va orizing the gasolene and `mixing it with t 1e' air, to rovide improved meansor l controlling the ow of air theretlirougl1,and

to provide the device with various new and useful featuresV hereinafter more fully described and particularly pointed -out inthe claims, reference being had to the-'accompanying drawings, in which:

Figure 1. is a side elevation of-a device embodying my invention with the tank shown in vertical section; Fig. 2. an enlarged view of my improved carbureter shown in vertical section; ig. l 3. a plan view of the same Fig. 4. a modification of the same in vertical section; and, Fig. 5. va detail of a part of the gasolene pipe.

lLike numbers refer to like parts 'in all-of the figures. i

1 represents thejcase of thedevice consistl ing of a horizontally extended hollow body provided with an-'a1r1inletopening 2 at one side and near one end, 'and an exit openin 3 provided with means'adapted to connect` t e devicev with an internal combustion engine.

,4 is a pi e toconvey lgasolene from the" .tank to a c amber located at the fend ofthe case opposite the exit 3. In this chamber is' a nee le'valve 5to admitthe flow of gasoi `lene through a nozzle 5 opening into the case close below. the 'inletvalve and arranged sub,

. substantially at right anxslde y e eirfinlet 'Opening 0f. the. valve# Above the valve 5 and opposite said opening is a secondv needle valve 16, which discharges an auxiliary supply of gasolene through theV opening 7a whenever the valve 7 is wideopen. This stream is also projected across vthe current oi air and thus sprayed` and more or less evaporated thereby before falling into the depression 6. `A .valve similar tothe valve 7 is provided atthe exit opening 3 to adjust the same.

c5 These valves 7 and 8 are provided with levers 9 and 10 to simultaneously adjust the valves, the leversbeing connected by a rod 11 to which is pivotally attached a connection rod 12 extending to any convenient operating means whereby thel valves 7 and 8 are simultaneously operatedto adjust the openings 2 and 3 and thus control the flow of airthrough the device'.

To limit and regulate the flow of gasolene to the carbureter, an air pipe 13 extends from near the top of the tank, and above the gasolene, down within the 'case toa re-de termined line in the'depression an when the gasolene fills the depression up to the `end of this pipe, the air 'liowingjinto the tank 15 will be cut oil thereby and the further flow of gasolene from the tank to the carburetor is revented. The gasolene is thus constant y maintained at a pre- ,determined level in the carbureter. To adjust this pipe 13 vertically and thus change the quantity .of gasolene in the depression 6', said pipe is inserted in a sleeve 14 having a vertical screw adjustment in the case, whereby. the lower end of the pipemay be adjusted relatively tothe case by turning the said sleeve. To permit thisgadjustment, the

soA

pipe 4 is provided with a series of elbows and i nipplesfla whereby the distance' `.between the tank and the carburetefmay be lvaried with-A out ail'ecting the operation of the pipe 4'.'

- To fill. the tank 15, and Vto maintain the same vairtight, to enable the air pipe tore ulate the iiow, a plug, 17 is l`inserted in a col ar -18 mounted on, the tank and this plug 'is sur.-V

rounded by packing 19 englagedby the iiange of the plug, and to furt joint, the' upper end ofthe plug is threaded vas at 21,jan'd-a c ap 20 covers thisplug", and

has an innerrthread engagingthe plug' and is er insure a tight l held vdown therebylwithfits rim upon the packing, vthus.'securing. a double packed jointfto keepout the i In, 4the modifiedfconstructionshown the -Fig.'4., b .\tl:i' pip'es 13 and 45ers insertedin the vertically adj ustable' sleeve 14 2 h6-Walvis .case by means of theisleeve 2. The combination of. a case, an air inlet Y 5 is placed in theplug, and the nozzle 5b extends vertically therefrom, and discharges the gasolene-vertically across the horizontal current of air passing over the gasolene inthe depression 6. This 'modication simplifies 1. The combination of a'case having a de'-I pression in the Ibottom thereof, means for admittinga current of air to the case, means for `removing av combustible mixture from the case, a vertically adjustable sleeve in 'the case, a 'nozzle in the case, an air tight tank above the case, a pipe-connecting the bottoni of the tank andthe nozzle and having meansl for'longitudinal ez'qpansion, a pipe extending from the/'depression to the upper part of the tankand vertically adjusted relative tothe valve the case -andyhaving openings for air and for gasolene, a gasolene valvel outside the'v-,air valveJ means for supplying gasolene to both of said valvesjmeans for removmiglia-combustible mixture from the case; and means for closing the gasoleneopening of the Alene only when saidlair valve is'nearly or quite open, a nozzle below sa1d valve,4 means for supplying gasolene to said valve and nozzle, and means for removinga combustible" mixture from the case.

4.- AThe Vcombination of a case, an air valve near oneendof the case, and having a side opening to admit gasolene only when said air valve is nearlyv o1' quite wide open, a nozzle below said air-valve, anair ti ht tank, a pipe connectingthe lower parto the tank with the valve and nozzle, a A.pipe connecting the lower part o f the case and the upper part of the tank,. andy means for removing a combustible mixture from the case'. n
